TL;DR: In this paper, a camera system having an interchangeable objective lens selectively mountable to at least two different types of camera bodies of a, first type and second type, is involved, and a register is provided in the camera body for storing a selected compensation data which is necessary for the type of camera body mounted with the lens.
Abstract: A camera system having an interchangeable objective lens selectively mountable to at least two different types of camera bodies of a, first type and second type, is involved. The camera system has a ROM located in the interchangeable objective lens for storing a plurality of compensation data: one is suitable for the first type camera body; and the other is suitable for the second type camera body. Each data compensates an error in fully-open aperture light measurement for each type of camera. The compensation data is transmitted from the lens to the camera body. A register is provided in the camera body for storing a selected compensation data which is necessary for the type of camera body mounted with the lens. A device is provided in the camera body for practicing a fully-open aperture light measurement through the interchangeable objective lens to produce a light measuring information including the light measurement error. A calculator is provided in the camera body for calculating a correct exposure information using the compensation data stored in the register and the light measuring signal, whereby the error included in the light measuring signal can be removed.

TL;DR: In this article, a device for mixing video and audio signals originated from at least one remote camera and one director camera including a main unit having a circuit for synchronizing the video signals of the remote and director cameras, and a circuit combining these signals through the use of removable special effects cartridges or subassemblies that are pre-programmed for predetermined video switching patterns.
Abstract: A device for mixing video and audio signals originated from at least one remote camera and one director camera including a main unit having a circuit for synchronizing the video signals of the remote and director cameras, and a circuit for combining these signals through the use of removable special effects cartridges or subassemblies that are pre-programmed for predetermined video switching patterns. The circuit for synchronizing the video signals separates the sync signals from the director and remote cameras, locks the vertical, horizontal and color subcarrier on the director camera from the remote camera. The device is connected through junction box to director camera and video tape recorder, and directly to remote camera.

TL;DR: In this paper, the car industry is using high speed photography for crash testing and other dynamic testing of components, where high speed cameras with frame rates between 400 and 1000 frames per second are being used, whereas the time period to be measured is in the range of about 100 - 250 ms.
